A client who is 8 weeks pregnant tells the nurse, "I find that I'm always going to the bathroom to urinate." Which response by the nurse would be appropriate?

"Your baby is making urine so this is adding to what's in your bladder."

"Your kidneys now have less cells to filter the fluid that goes through"

"Your growing uterus is putting pressure on your bladder causing you to go"

"Your urine is more concentrated now, so you have to go more often"
